Patent FR-2221387-A1 (FR)
Title: Rail-mounted lifting equipment travel retarder - has lug raising counterweight via rope on striking stop on rails
IPC: B66C9/18
Filed: 1972-07-28
Abstract: The mechanism is particularly for tower cranes, and helps the travel braking system. As the crane travels along the rails, lugs on its chassis come up against stops on the rails, and in so doing haul on ropes reeved over pulleys so as to raise the counterweight on the chassis. The energy involved is thus dissipated in lifting the weight, slowing the travel speed down virtually to nil when the brakes are supplied, and eliminating any shock loads. The weight itself can be that used to stabilise the chassis. The lugs can be in the form of levers pivoting on the crane chassis bogies, acting against stops in the form of bars across the track.

Title: Laminated paper on Fourdrinier screen prodn. - by forming auxiliary paper webs on drums in contact with screen
IPC: D21F11/04
Filed: 1973-06-28
Abstract: Paper pulp is deposited onto a fourdrinier screen to form a base paper web, and paper pulp is also deposited onto the surface of >=1 pref. perforated drums in contact with the base paper web on the screen, whereby an auxiliary paper web formed on each drum surface is pressed onto and combined with the base paper web.

Patent FR-2203232-A1 (FR)
IPC: H01L21/822
Filed: 1973-09-06
Abstract: A generalized and modular logic system for all arithmetic/logical units of a digital computer. Each arithmetic/logical unit of a computer is partitioned into sections formed of combinational logic networks and storage circuitry. The storage circuitry is sequential in operation and employs clocked dc latches. Two or more synchronous, non-overlapping, independent system clock trains are used to control the latches. A single-sided delay dependency is imparted to the system. The feedback connections from the respective latch circuitry are made through combinational logic to other latch circuitry that has a system clock other than the system clock acting on the initiating latch circuitry. With each latch, there is provided additional circuitry so that each latch acts as one position of a shift register having input/output and shift controls that are independent of the system clocks and the system inputs/outputs. All of the shift register latches are coupled together into a single shift register.

Title: Continuous welding of tube made from metal strip - with offset grinding wheels for continuous dressing of pulley electrode
IPC: B23K11/00
Filed: 1974-06-18

The novelty is that a row of offset grinding spindles is mounted above the pulley for periodic or continuous dressing of the gap, the groove-profile and the periphery, the grinding wheels being of an electrically-insulating matl. Three spindles and grinding wheels are used, a doomed-wheel for the groove profile, a thin wheel for the gap and a plain wheel for the periphery of the pulley. By using probes or sensors, an automatic sequence can be established for dressing the pulley and adjusting its location w.r.t. the tube.
